Both posts are very well thought out. I always mistrust polls and any statistics that don't publish details of their methodology and raw data.
Sometime back I spent some involuntary time in the army. We had to take a number of tests. I answered most of them randomly.
On the IQ test, I really tried h a r d to get all the questions wrong, in the vain that they will think I was an idiot and they let me go (they never did and no-one ever gave me a strange look).
I sympathize with those Oklahoma kids and understand that there many ways to tell a grown-up a 'fuck you' ;)
